SHOCK-LOADER.

SPECIFICATION forming part of Letters Patent No. 769,302, dated September 6, 1904. Application filed January 25, 1904. Serial No. 190,568. (No model.)

To all whom, it may concern.-

Be it known that I, ELLERY CARROLL, a citi zen of the United States, residing at Morrow, in the county of Warren and State of Ohio, have invented certain new and useful Improvements in Shock-Loaders, of which the following is a specification."

This invention has relation to loading apparatus designed chiefly for use in the field for lifting shocks and depositing the same in a wagon or like carrier with which the loader is associated.

An essential feature of the invention is to utilize the draft of the machine as means for elevating'the load, swinging the same to aposition over the wagon or carrier, and for automatically throwing the actuating mechanism out of gear preliminary to the load into the wagon or carrier.

The invention contemplates in combination the actuating mechanism, a brake having ratchet connectionwith the shaft of the drum to admit'of free rotation of the latter when elevating the load and swinging the same to a position for proper discharge, said brake holding the drum against backward rotation when the actuating mechanism is thrown out of gear and permitting the attendant to control the descent of the load-when lowered into the Wagon or carrier.

The improvement consists, essentially, of the structural features and novel details of construction, which hereinafter will be more particularly set forth, illustrated, and finally claimed.

In the drawings hereto attached and form- 'ing a part of the specification, Figure l is a perspective View of .a shock-loader embodying the invention, the inner ground-wheel being omitted to show more clearly the relative arrangement oftheparts, and the hoistingrope being attached to the shock preparatory to elevating the same by a forward movement of the machine. Fig. '2 is atop plan view. of the loader. Fig. 3 is a detail view of the needle-bar" for threading the rope through the shock when applying the same thereto. Fig. 4 is a detail perspective view of the binder as it appears when applied to a shock. Fig. 5

is a detail view of the gearing for transmitting motion from the shaft or axle to the drum or Windlass. Fig. 6 is a detail view of the brake mechanism.

Corresponding and like partsare referred to in the following description and indicated ;in all the views of the drawings by the same reference characters.

The framework of the truck comprises longitudinal beam 1, transverse beam 2, bulltongue' 3, braces 4, post 5, and stays 6, the latter being outwardly diverged and having their outer ends connected by guys 7 with the upper end of the post 5. Other guys, 7, connect the ends of the bull-tongue 3 with the upper end of post 5. The axle 8 is arranged beneath the transverse beam 2 and is mounted in bearings applied to the-framework, so as to turn freely. :The ground-wheels 9 are loosely mounted upon the spindles or arms of the axle and are conhected to the latter by the usual ratchet mechanism to admit of relative backward movement of the ground-wheels.

A gear-wheel 10 is secured to the axle 8, so as to rotate therewith, and is adapted to mesh with the teeth of a companion gear-Wheel 11, secured to the shaft 12, paralleling the axle 8 and .journaled in bearings applied to the framework. The shaft 12 is movable to admit of the gear-wheel 11 being thrown into and out of contact with the gear-wheel 10. In the preferable construction the bearing 13, supporting the end of the shaft 12, carrying the gear-wheel 11, is slidably mounted and held in place by suitable means, as the keeper 14:. A lever 15 is fulcrumed to thelongitudinal beam adjacent to the gear-wheels and is connected by link'16 with the bearing 13. Proper manipulation of the lever 15 admits of throwing the gear-wheel 11 intoand out of mesh with the teeth of the gear-wheel 10, whereby the loading apparatus may be thrown into and out of gear. Thedrum or Windlass '17 is 'mounted upon the shaft 12, so. as to rotate therewith, and the hoisting-rope 18 is adapted to wind thereon. This drum or Windlass is preferably tapered, and the hoisting-rope winds thereon from the larger toward the smaller end, thereby imparting a rapid movement to the rope when first starting the machine, so as to quickly take up slack and tighten the parts.

The crane comprises the post 19, arm 20, and brace 21. The hoisting-rope 18 passes over sheaves 22 at opposite ends of the arm and is provided at its attaching end with a binder for securing the load or shock. An arm 23 projects laterally from the post 19 and is movable therewith and is provided at or near its extremity with a sheave-pulley 2 1. A companion arm 25 is rigidly connected to the post 5 and extends therefrom, and one end of a cord or flexible connection 26 is attached thereto, the other end of said connection being at tached to the lever 27, pivoted to the crane and extended therefrom. The connection 26 passes around the sheave-pulley 24E intermediate of its ends, so that an upward movement of the lever 27 at its free end pulls upon the connection 26 and effects a swinging of the crane, so as to bring the load over the body 28 of the wagon or carrier. The lever 27 is about in the plane of the crane and normally inclines downward toward its outer end, which is forked, as shown at 28, to receive the vertical portion of the hoisting-rope, thereby insuring contact of the load or shock with the free end of the lever and a movement thereof with the load, so as to swing the crane and simultaneously throw the machine out of gear.

The following means have been devised to effect automatic unshipping of the operating mechanism, namely: swingletree or equalizing-lever 29, pivotally connected intermediate of its ends to an extension of the rear stay 6, cord or flexible connection 30 between the lever 15 and one end of the part 29, a cord or flexible connection 31, attached to the opposite end of the part 29 and passed over pulley 32 at or near the base of the crane and extended upward and made fast to the lever 27. When the outer lower end of the lever 27 is elevated by contact of the load therewith, the cord or flexible connection 31 is drawn upon and causes the lever or swingletree 29 to turn and to correspondingly move lever 15 through the connection 30, thereby throwing gearwheel 11 away or out of contact with the gear- Wheel 10.

The brake mechanism comprises brakewheel 33 and brake- levers 34 and 35, which are pivoted to each other and to the framework of the machine and arranged to grip opposite sides of the brake-wheel 33. The brakewheel 33 is loosely mounted upon the shaft 12 and is connected therewith by ratchet means, the same consisting of the ratchetwheel- 36, secured to the shaft, and spring-actuated pawls 37, pivoted to the brake-wheel. The brake-levers are adapted to be forcibly drawn together by means of the lever 38, fulcrumed to one of the brake-levers, as 35, and connected by spring 35 to the opposite brake-lever and held in an adjusted position by the hand-latch 39 engaging with a tooth of the segment 10. When the shaft 12 is turned so as to wind the hoisting-rope 18 on the drum or Windlass 17 and the brake-wheel is held fast by application of the brake-levers 34: and 35, the ratchet-wheel 36 turns with the shaft and the pawls 37 ride upon the teeth thereof. hen the machine is automatically thrown out of gear, the load is held suspended solely by means of the brake mechanism, which provents backward rotation of the shaft 12 and drum or Windlass 17. By proper manipulation of the lever 38 the brake-wheel 33 may be released more or less, so as to permit gradual descent of the load into the wagon or carrier.

The attaching portion of the hoisting-rope 18 is branched or composed of two parts 11, having rings or analogous attaching means at their free ends to make connection with hooks 12 at opposite sides of a bar 43, constituting an essential part of the binder. These ropes or branches 41 are threaded through the shock a4. by means of the needle-bar 4.5, and the end portions are passed around the parts of the shock in opposite directions and engage with the bar 4:3. The bar 13 is provided at one end with a sheave 46, around which the hoisting-rope or parts 11 thereof pass. The opposite end of the bar 43 is provided with spurs or teeth 4:7 to be pressed. into the shock or load, so as to make positive engagement therewith and prevent slipping. Stay-bars 18 are pivoted at one end to the end portion of the bar 13, provided with the teeth 17, and a coilspring 49 connects the stay-bars with the bar 4.3 to normally cause the stay-bars to fold thereon. Jaws 50 are applied to the stay-bars 18 intermediate of their ends and are adapted to grip the hoisting-rope and transfer a part of the lifting force to the upper end of the shock, so as to insure a turning or upsetting thereof upon initial application of lifting force to the hoisting-rope, thereby preventing slipping or upward displacement of the rope upon the shock when first drawn upon and insuring a tightening of the rope about the base portion of the shock. After the shock has been upset the rope 18 automatically clears the jaws 50. and the spring 49 folds the stay-bars 48 upon the bar 43 and the shock is elevated, occupyingapproximately a horizontal instead of an upright position.

Aloader embodying the invention normally has the parts occupying the relative position about as shown in Fig. 1-that is, with the lever 27 laterally and dmvnwardly inclined and the crane about ataright angle to the direction of movement of the machine. After the hoisting-rope has been attached to the load or shock in substantially the manner set forth the brake mechanism is set, and upon upward movement of the machine by driving the team attached to the wagon or carrier to which the loader is coupled the shaft 12' is rotated and the hoisting-rope is wound'upon the drum or Windlass 17 thereby lifting the load or shock from the ground, and as the load approaches the limit of its upward movement it comes in contact with the forked ends of the lever 27 and carries the same upward, thereby drawing upon the flexible connections 26 and 31, with the result that the crane is swung so as to bring the load over the wagon and the operating mechanism thrown out of gear. At this stage of the operation the load is held suspended by the brake mechanism, the pawls 37 engaging with the teeth of the ratchet-wheel 36 and preventing backward rotation of the shaft 12 and Windlass 17 By proper manipulation of the lever 38, as stated,

the brake may be relaxed and the loadper-- mitted to descend into the wagon or carrier.

Having thus described the invention, what is claimed as new is 1. In a loader, the combination of a support, a swinging crane, arms extended from the crane and support, a movable element adapted to be. automatically actuated upon the ascent of the load, and connecting means between the said arms and movable element to effect automatic swinging of the crane to bring the load in determinate position, substantially as set forth. v v

2. In a loader, thecombination of the hoisting mechanism, a movable element actuated upon ascent of the load, operating-gearing comprising a movable gear element, a lever adapted to be operated by hand connected with said gear element to effect movement thereof, and connecting means between said lever and the first-mentioned movable element, whereby the hoisting mechanism is automaticallg thrown out of gear, substantially as specifie 3. In a loader, the combination of a swinging crane, hoisting mechanism cooperating therewith, a pivoted lever, connections between said pivoted lever and the crane and post, andother connections between the pivoted lever and the drive-gearing of the hoisting mechanism to automatically effect a swinging of the crane and a throwing of the hoisting mechanism out of gear simultaneously with the ascent of the load, substantially as described.

4:. In a loader, a binder comprising a bar,a rope or flexible connection at one end of said bar, and a stay connected to the opposite end of said bar and provided with jaws to grip the rope and automatically release the same, substantially as and for the purpose set forth.

In testimony whereof I afiix my signature in presence of two witnesses.
